The reaction of glyoxal with nucleophilic amino acids was monitored for β-casein as well as β-lactoglobulin. As predicted from previous experiments with hippuryl amino acids, a measurable decrease of arginine can be found in the thiol-free β-casein, while the lysine content remained almost unchanged. For β-lactoglobulin, the incubation with glyoxal led to a slight decrease in the lysine content...

The unfolding of β-lactoglobulin (β-lac) upon heating was comprehensively studied through molecular dynamics computer simulations. A β-lac molecule in the aqueous solution firstly heated at 500 K for and then annealed 300 to collect stable conformations. There were five meta-stable conformations observed based on Free Energy Landscape (FEL). found exhibit an open extended conformation followed ...

Actinidin was used to hydrolyse proteins in whey protein isolate (WPI) and milk concentrate (MPC) reduce immunoreactivity of β-lactoglobulin (β-LG) αs1-casein (αs1-CN). Samples were incubated at an enzyme substrate ratio 1:100 (5.21 units actinidin activity g−1 protein) 10 or 60 °C for up 31 5 h, respectively. Protein hydrolysis determined by the degree SDS-PAGE. Antigenicity hydrolysates β-LG ...

our previous study reported that lactobacillus acidophilus ( l.acidophilus )  key laboratory of dairy science  (klds) 1.0738 had an effective impact on inhibiting β-lactoglobulin (β-lg) allergy. this study further investigated the anti-allergic activity of peptidoglycan (pgn) isolated from klds 1.0738. this study aimed to assess whether toll-like receptor 2 (tlr2)/nf-kappab (nf-κb) signaling ac...

The aim of the present study was to get a total physical and chemical characterization and comparison of the principal components in Bangladeshi buffalo (B), Holstein cross (HX), Indigenous cattle (IC) and Red Chittagong Cattle (RCC) milk. Protein and casein (CN) composition and type, casein micellar size (CMS), naturally occurring peptides, free amino acids, fat, milk fat globule size (MFGS), ...
